Boston’s developers fight rising seas

With half of Boston built on lowlying landfill, the city is raising streets, building berms and even requiring that new highrises on its harbour acquire “aqua fences.” If the weather forecast is ominous, a Bobcat loader will carry the 160 1.2-metre-high barriers out from the basement to be fastened to the sidewalks. In the first test, it took 15 to 20 workers eight hours to assemble the barrier.
